I would be happy to help with this question!
you would need to use the pythagorean theorem inputting 3.5 for a and 15 for c. after this you will need to solve for b and you should get the answer of 14.6feet

Answer


= 14.6 feet


Step-by-step explanation

The length of the ladder is 15 feet and it is place against the wall 3.5 feet from the base of the wall.

This makes a right triangle with a base length of 3.5 feet and a hypotenuse of 15 feet.

So, we can use the pythagorean theorem to calculate the height required.

a² = c² - b²

Where a and b are the legs of the right triangle and c is the hypotenuse.

a² = c² - b²

h² = 15² - 3.5²

h² = 225 -12.25

= 212.75


h = √212.75

= 14.58595215
